PATENT C. G. SARGENT, OF LOW'ELL, MASSACHUSETTS.

Specilicaton forming part'of Letters Patent l\`o. 5,0ll, dated March13,1547.

lo a/ZZ whom, il? may concern:

Be it known that I, O. G. SARGENT, of Lowell, in the county of Middlesexand Statevof Massachusetts, have inventeda new and useful Improvement inthe Machine for Combing Wool; and I do hereby declare that the followingis a full, clear, and exact description of the v principle or characterwhich distinguishes it from all other thingsbefore known and of themanner of making, constructing, and using the same, reference being hadto the accompanying drawings, making part of this speciiication, inwhich- Figure lis afront elevation of the machine; Fig. 2, an endelevation; Fig. 3, a vertical section taken at the line x x of Fig. l;and Fig. 4, a back elevation of one end of the machine.

The same letters indicate like parts in all the figures.

The nature of my invention consists in attaching the comb-teeth to aseries of plates that are caused to slide along in front of the cylinderof cards, anda pair of rollers for the iibers to be acted upon, andstripped from the teeth, and are then shifted in a parallel position toslide back to the end from whence they first started, and there shiftedback to pass along as at first, a hollow box through which steamor`heated air circulates being placed betweenv the comb-teeth and thecylinder of cards, and little below the points of the comb-teeth for thepurpose of keeping the bers at the required temperatnre while underoperation in the machine.

In the accompanying drawings, a represents the frame of the machine,properly adapted, as shown in the drawings, to the purpose intended; andb, a cylinder of cards, made in the usual manner, to which the wool issupplied by a small card-cylinder, b', or in any way desired, as thismakes no part of my invention. The comb-teeth c, on which the wool is tobe combed, are attached to and project from the upper surface, and nearone edge of a series of metal plates, cl, which are `formed, asrepresented in the drawings. to fit and slide freely in a groove made ina bar, e, placed in front of the cylinder of cards and parallel with itsaxis, and at such a height as to bring the points of the teeth at therequired height in iront of the cards-say a little below ahorizontalline radiating from the axis of the cylinder-so that the card-teethshall touch the body of the comb-teeth without catching onto theirpoints; and to admit of this that part of the plate d to which thecomb-teeth are attached projects over and runs on top of the bar e. Thelower part of the plates d is provided with rack-teeth, into'wliich thecogsof two pinions, I f, (one only of which is shownV in the drawings',)on the upper ends of the two vertical ar'- bors g g, one at each end,mesh, the diameter of these pinions being such as to have their cogs acton the rack on the two ranges of combplates, so as to carry them forwardand back. As each plate reaches the end of itscourse in the bar e, it ispressed upon by a spring, h, attached by one end to the bar, the otherpassing through an aperture to bear onto the back of each plate, which,as itpasses out of its groove in the bar, enters a corresponding ygroove, i, in a cylinder, j, the axle of which is provided with journalsthat run in appropriate boxes in the frame, and as the plate passes intothis groove it forces back a lever, Z, that has its fulcrum at m, aspring, n, keeping it up against the end ofthe cylinder.

From the foregoing it will be obvious that so soon as the plate isentirely out of the groove in the bar and in the groove of the cylinder,the end cog of the rack only is engaged with the cogs of the pinion,which by its rotation forces it forward, aided by the spring l1, untilit comesv in line with a groove in another bar, o, similar to andparallel with the bar e, and then the spring-lever l forces it into thisgrooveaided by the action of the pinion-cogs on the rack. and so soon asthe pinion is fairly engaged with the rack the plate is carried back tothe other end of the machine by the pinion, unaided by the spring-lever,which remains in its ori'ginal-positin prepared to perform the sameoffice on the next plate, the cylinder j being of sufficient diameterand provided with the required number of grooves for the purposeintended. The other end of the machine is provided with the likearrangement of parts, but reversed to transfer the plates from the frontbar, o, to the back main bar, e.

The vertical arborsg ghave each at theirlower ends abeveled pinion, p p,the cogs of which engage with the cogs of two similar pinions, q q, on ahorizontal line-shaft, r, to insure the turning of the two arbors withequal velocity, the line-shaft receiving motion bythe train of Wheels st u, from the main driving-shaftv,

which also communicates motion to the combl ing-cylinder by a belt, w,another belt, x, communicating motion from this to the smallcard-cylinder b', which supplies the woolen fibers to the main cylinder.As the combteeth leave the combing-cylinder they pass by two rollers, g/z, which strip the combed fibers from them and deliver them in the formof a sliver. One of these rollers, y, is iiuted, and receives motionfrom the line-shaft by means of the two beveled cogged wheels ca and thespur-wheels c c', andthe other, z, turns freely in boxes d d in thejointed arms e e', and the surface of t-his latter roller is pressedagainst the other by a spring, f', the ends of which bear against thearms e e, its tension being regulated by a set-screw, g.

It will be obvious that this inode of moving and transferring the platesof combteeth may be employed in connection with a combing, carding, orbrushing cylinder, or any two or Vall three of them in succession, andthat the bers may be applied and removed fromthem by any means'desired,as these make no part of my invention and that, instead of using thegrooved cylinders at the ends' of the machine to transfer the platesfrom one of the groovcd bars to the other and back again, slides may besubstituted, moving either horizontally, vertically, or in any otherdirection; or that they may be made to slide in appropriate grooves orslides, as I do not limit my invention to the precise arrangement ofmachinery for effecting the transfer.

That I claim, therefore, as my invention, and desire to secure byLetters Patent, is-

Making the series of plates that carry the comb-teeth continuous intheir action by transferring them at each end from one groove or set ofways to another' and back again, substantially as herein described.
